Please don't put salt on my wound

Encountered a careless mistake few months ago,
it was not completely my fault,
but a mistake by someone else,
out of my control,
and only discovered after the meeting,
thus I needed to contact the oversea visitors telling them they had mistaken my belongings.
I needed to make a lot of effort to get back the item.

I knew very well it was not my fault,
but I also knew that I could do better to control it and avoid it happened.
I didn't feel good for long time.

Today,
S brought out this issue,
actually it was none of his business,
and he did remind me of my bad experience.

Please, please,
mind your own business,
and don't put salt on my wound!
